Passing Props with NavLink in React-Router-Dom Version 6

React-Router-Dom is a powerful library for routing in React applications. However, when upgrading from version 5 to version 6, developers may face some changes in how they pass props through navigation links. If you've recently upgraded and found yourself puzzled over how to maintain the same functionality as before, you're in the right place! In this post, we’ll uncover the updated approach for passing props with NavLink and how to retrieve them effectively.

The Problem: Props Not Passing with NavLink

In version 5 of React-Router-Dom, passing state through the NavLink component was straightforward. You could easily supply state objects through the to prop, which allowed you to access them using the useLocation hook. Here’s how it was typically done:

However, after upgrading to version 6, many users have noticed that attempting to access the passed state via location.state may result in a null value. This can be frustrating, especially if you rely on this functionality to manage component states and reactions.

The Solution: Updated NavLink Usage

In react-router-dom version 6, the method for passing props with NavLink has experienced some changes. Here's how to do it correctly in the latest version:

Summary of Changes

To summarize, here’s the breakdown of the updates made from version 5 to version 6 for passing props:

Previous Method:
Used an object with pathname and state inside the to prop.

Updated Method:
Directly define the to prop as a string (the target route) and pass state as an object directly using state={{ myState: "myStateValue" }}.

Conclusion

Upgrading to the latest version of libraries can often bring about challenges, but with the right guidance, those hurdles can be cleared! By utilizing the new NavLink syntax and the useLocation hook for state access, React developers can continue to manage their component states seamlessly. Feel free to experiment with this method in your projects and see how it enhances your navigation experience in a React application. Happy coding!
